Subject: [PATCH] Integrate Spring Geode Logging with Spring Boot Logging and
 externalizes configuration.

* Deprecates the logback-include.xml file.
* Declare the logging context name as 'geodeLoggingContext'.
* Determines whether Spring Boot SLF4J Logback logging configuration (metadata) files are present on the application classpath.
* Applies custom logging configuration declared by the user in the spring-geode-logging.properties file on the application classpath.
* Conditionally includes SLF4J Logback logging configuration from Spring Boot.
* Includes Appenders, Loggers and Properties configuration metadata files from Spring Geode Starter Logging.

Resolves #117.
